PROCESS oF MANUFACTURING CAR- BURETED WATER GAS' William E. Steinwedell, Cleveland Heights, Ohio, asslgnor to The Gas Machinery.. Company, Cleveland, Ohio, a corporation of Ohio applicati@ April s, 193s, serialNo. 200,449`

4 Claims.

This invention particularly relates to improvements in the well-known methods of manufacturing carbureted water gas in a gas-making set including a generator, a carbureter, a superheater, and a seal, all connected in a well-known manner, and equipped with the usual fixtures such as pipes and valves for supplying .suitable media for blasting a fuel bed in the generator, and for making up and dow'n gas-making runs through the fuel bed, and for carbureting the water gas so made. My invention particularly relates to improvements in such processes in vwhich the carburetion is effected by the use of heavy oil, such as bunker oil, and lu which a down blasting is elected by admitting the'blastlng air to the top of the generator.

The invention is particularly applicable for working in that type of a carbureted water gas set in which the hot gas valves for controlling the direction of flow are located respectively, in 2,0 pipe connections between the top of the generator and the top of the carburetenand between CII the bottom of the generator and the top of the The ligure is a view, partly in elevation andv partly invertical section, of apparatus for manu facturing carbureted water gas by the use of my improved method.

Referring to the annexed drawing, a generatonA, a carbureter B and a superheater-C constituting carbureting apparatus, and a seal D are connected together in the well-known manner by a pipe E between the top of the generator and the top of the carbureter, a pipe F between the bottoms of the carbureter and superheater, a pipe G leading from the stack C' of the superheater C to the seal D, and a pipe H communicating with the bottom of the generator and with the pipe E adjacent the carbureter B. Pipe l controlled by valve l' and pipe 2 controlled by valve 55 spectively, feed into the air pipe l and the 2 are provided for feeding air into the bottoml pipe 2, respectively. A pipe 5 controlled by valve 5' feeds heavy oil into the top of the generator A. vThe pipe E is controlled by an up-run hot gas valve l and the pipe H by a down-run hot gas valve 6. 'I'he superheater stack C is controlled by valve 9. l

The manner of using the afore-described apparatus, when Working my improved process, consists in first preparing for forward or upward blasting by having all valves closed except the stack valve 9 and the up-run hot gas valve 1. Then the fuel bed in the generator A is blasted with air which is admitted by opening the valve I', and the resultant .blast gases which pass through the `connection E from the generator A to the carbureter B are burned by air admitted by opening the blast valve 3', this burning of the blast gases suitably heating the checkerwork in the carbureter B and superheater C. The resultant products are discharged through the open valve 9 of the stack C. f

Then the carbureter blast valve 3 is closed and, 'in succession, the generator blast valve I' and the superheater stack valve 9 are also closed, which places the apparatus in condition for an 11p-run.

The up-run is `effected by first opening the steam valve which effects the formation of blue water gas by the passage of the steam through the heated `fuel bed, which blue water gas is carbureted by heavy oil admitted by opening the valve 5', which heavy. oil is sprayed upon the fuel bed and is cracked and volatilized and mixes with the blue water gas issuing from the fuel bed and is permanently xed in the heated checkerbrick of the carbureter B and superheater C. The resultant gases pass through pipe G into the seal D. The up-run is terminated byllrst closing the oil valve 5' and then the up-run steam valve jl'. *y Then a down-run is effected by first opening the down-run hot gas valve. 6, then'closing the up-run hot gas valve l, and then opening the down-run steam valve 8', which results in the formation of blue water gas by the passage of steam downwardly through the fuel bed, which blue Water gas issues from the bottom of the generator and passes by pipe H into pipe E and thence through the carbureter B and the superheater C and through the pipe G into the seal D. 'I'he down-run is terminated by closing the steam valve 8. I

Then a down blow is effected by rst opening the stack valve 9, and then opening the blast valve 2 which effects a vdown-blow through the fuel bed of the generator A and the resultant products therefrom pass into the pipe H and then into the pipe E and thence through the` carbureter- Under some conditions when working the im-A proved process which has just been described, it may be deemed essential to effect a short blowrun during the up-blow. 'Ihis may be effected by closing the superheater stack valve 9 before .the bottom generator blast valve I is closed and y thus terminate the up-blow period by a short blow-run. v

Under some conditions, it may be deemed essential to add heavy oil to the fuel bed during part of the down-run, as well as to carburet the blue water gas during the up-run;v in which case, the oil valve 5', instead of being closed at the termination of the up-run, can be allowed to remain open during part of the down-run, and then this oil valve 5' can be closed at any desired time after opening the down-run steam'valve 8.

Under some conditions, it may be desired to make a short down-blow run; it which case, the top generator blast valve 2', which furnishes the air for the blast downwardly through the fuel bed, may be opened, after the termination of the `down steam run,v and before the opening of the stack valve 9, and thus the down-blow gases pass through the connections H and E and thence through the carbureter B and superheater C and thence into the seal D through the pipe G, for a short period, and then the stack valve 9 is opened.

What I claim is:

l. The process of manufacturing carbureted water gas, with the use of heavy oil as the carbureting medium, in a gas-making set including a generator, conduits connecting the top of the generator and the bottom of the generator, re-- spectively, with the carbureting apparatus, and flow-direction control valves disposed in said conduits between the generator and the carbureting apparatus, consisting in first upwardly blasting the fuel bed in the generator with air admitted at the bottom of the generator and burning the blast gases in the carbureting apparatus with air admitted to the latter and passed therethrough then effecting a steam run upwardly through the fuel bed with steam admitted at the bottom of the generator and simultaneously spraying heavy oil upon the top of the fuel bed,

and passing the resultant gaseous products through the carbureting apparatus then eifecting a steam run downwardly through the fuel bedvwith steam admitted at the top of the generator and passing theiresultant gaseous products through the carbureting apparatus and then blasting downwardly through the fuel bed with air admitted to the set at the top of the generator and passing the blast gases through the carbureting apparatus.

2. The process, as set forth in claim 1, in which the upward blasting terminates with a short upblow run after shutting off the air being admitted to the carbureting apparatus.

3. The process, as set forth in claim 1, in which the spraying of heavy oil upon the top of the fuel bed is continued into and through a part of the down steam run.

4. The process of manufacturing carbureted water gas, with the use of heavy oil as the carbureting medium, in a gas-making set including generator, carbureter, and superheater shells, and a seal, conduits connecting said shells and said seal in series, including conduits connecting the top of the generator and the bottom of the generator, respectively, with the carbureter, and flow-direction control valves disposed in said conduits between the generator and the carbureter, consisting in first upwardly blasting the fuel bed in the generator with air admitted at the botton of the generator and burning the blast gases in the carbureter and superheater with air adumitted at the-'top of the carbureter, and exhausting the waste gases from the set, then eecting a steam run upwardly through the fuel bed with steam admitted at the bottom of the generator and simultaneously spraying heavy oil upon the top of the fuel bed, and passing the resultant gaseous products through the carbureter and superheater to the seal, then effecting a steam run y downwardly through the fuel bed with steam admittedat the top of the generator and passing the resultant gaseous products through the ca'rbureter and superheater to the seal, then effecting a short down blow run Vthrough the fuel bed with air admitted to the set at the top of the generator and passing the resultant 'products through the carbureter and superheater to the seal, and then continuing the said down blow through the fuel bed and passing the blast gases through the carbureter and superheater and thence exhausting them from the set.
